产品族规划需要建立一个基于设计域的全局概念和逻辑体系。通过探索表征产品设计域的客户需求、功能属性、结构设计参数以及过程参数之间所固有的灵敏度关系,得到确定产品平台特征和产品族规划的依据,并通过规划家用轿车这一具有复杂的功能结构对应关系的产品实例,验证了该方法的有效性及所具有的实用价值。提出的产品族规划方法整合了企业产品生产过程各环节的数据,为企业市场人员、设计者、产品工程师、决策者等不同的参与者在产品族设计过程中搭建了一个能进行良好沟通的平台,是一个符合企业实际需要的系统化方法。
In order to achieve system-wide solution for platform-based product family design, any design method should set up the decision framework along the entire spectrum of product realization according to the concept of design domains. The method presented is explored through sensitivity analysis which helps to quantify the cascading mappings between customers’ requirements, functional requirements, design parameters and process variables. Based on analyzing customers’ needs, the product platform characteristics are identified by using the sensitivity analysis results which integrate various information from all the design domains. By way of illustration, a family of sedan is designed and its results demonstrate the effectiveness and practical value of the method.
